--------------------------------------

Maeda Atsuko - Maeda Atsuko (The opposite of the glasses...Strongest!):
The mysterious transfer student that has come to Maji High. Always diligently aiming to become a nurse but becomes the strongest by hearing the words 'maji'

Consists of:
Bungee - Nitou Moeno
Akicha - Takajou Aki
Wota - Sashihara Rino
Unagi - Kitahara Rie

Kabuki Sisters (Gonna Kabuki*** tonight too~):
Consists of:
Oo Kabuki - Kasai Tomomi
Shou Kabuki - Kuramochi Asuka
These sisters wearing Kabuki makeup that fight with no rules. The older sister's weapon is the bottom of her palm. The younger sister's specialty is explanation.

Sanshou Shimai (3 girls with a fighting style of cruel angels):
Consists of:
Manamana - Oku Manami
Myao - Miyazaki Miho
Rabutan - Oota Aika
May seem small, but underestimating them would be painful. A 1st year group that fights cruelly while laughing. Close with Shiten'ou**** Shibuya.

Nezumi - Watanabe Mayu (The evil brains peeking from her parka):
Managing the information, she schemes from behind the scenes. Aims for the top with her intellect!

Choukoku - Akimoto Sayaka (The strongest lone wolf of the Hyakunin Isshu world):
Leaves one poem of the Hyakunin Isshu***** after winning a fight. The lone wolf that has mastered karate.

Gakuran - Miyazawa Sae (The most "manly" in Maji High):
Thinks she herself is a guy. Fights Maeda in order to steal Daruma. Seems like love.

Minegishi Minami - Minegishi Minami (The student president of justice!):
The self-proclaimed (?) President. "I'm the student president starting from yesterday." Dislikes crooked things.

Onizuka Daruma - Nachu (I'm the one who'll protect Atsu-nee!):
Forcibly declaring herself as Maeda's disciple out of admiration of Maeda's strength. Not actually all that strong in fights, but follows Maeda out of adoration.

Yuko-senpai - Oshima Yuko (The strongest yankii that holds the school together):
The president of the wind instrument club "Rappappa" that holds Maji High together. The strongest beauty that even the yakuza acknowledge. Currently in the hospital.

Sado - Shinoda Mariko (That sadistic fighting style is the worst!):
The leader of Rappappa that controls the Shiten'ou. Protecting the school in Yuko's absence; a woman with a strong sense of duty.

Black - Kashiwagi Yuki (That interior...Pitch black?!)*:
Movements are amazingly fast. Bids farewell with a poem and a death sentence to defeated opponents.

Gekikara - Matsui Rena (Missing in action but...don't forget me?):
Enjoys a cruel fight. Was in reform school but should be coming back soon...

Torigoya - Kojima Haruna (Chicken...?!):
The most eccentric within the Shiten'ou. Her past involves chickens but what??

Shibuya - Itano Tomomi (Don't underestimate the devilish girl?):
The most stubborn within the Shiten'ou. Does her own thing using her disciples.

Translator's notes:
* - referring to Black being black-hearted.
** - basically fried beef or pork giblets.
*** - Kabuki
**** - the title referring to the 4 strongest directly under Yuko-senpai and Sado.
***** - 100 poems by 100 famous poets

To be honest, there's some parts that I'm not too satisfied with (bonus points if you can point them out!) but I couldn't think of a way to translate it otherwise..
